Scientists are one step closer to creating a real-life version of Dr. Seuss‘ green eggs and ham, thanks to the birth of ten transgenic pigs in late December that glow green when placed under a black light. Zhenfang Wu and Zicong Li of the South China Agricultural University used a technique developed by reproductive scientists from the University of Hawaii at Manoa’s John A. Burns School of Medicine to transfer plasmids (small DNA molecules, separate from the chromosomal DNA within a cell) carrying a fluorescent protein from jellyfish DNA into the pig embryos.
